"Unchained Melody" is a 1955 song with music by Alex North and lyrics by Hy Zaret.
The best-known version of "Unchained Melody" was recorded by The Righteous Brothers and produced by Phil Spector in 1965 as the 'B' side of the single featuring the song, "Hung On You". Although the version was credited to The Righteous Brothers, it was actually performed as a solo by Righteous Brother Bobby Hatfield, who later recorded other versions credited solely to him. This recording climbed to number 4 on the Billboard Hot 100 chart in 1965 and reached number 14 in the UK in 1965.
"Unchained Melody" reappeared on the Billboard charts in 1990 after The Righteous Brothers' recording was used in the box office blockbuster film Ghost. Two versions charted in the US that year. There was the reissue of the 1965 original Righteous Brothers single which received a lot of airplay.This version peaked at number 13. There was also a 1990 re-recording of the song which was available only as a cassette single. For eight weeks, both versions were on the Hot 100 simultaneously.
It reached number 1 for the fifth time in the UK, becoming the UK's top selling single of 1990, and has since sold 1.04 million copies. It also reached number 1 in Australia, staying at number-one for seven weeks through November 1990 and into January 1991. In 2004 it finished at number 27 on AFI's 100 Years...100 Songs survey of top tunes in American cinema.
